a trend toward significanceP = 0.060
There was no significant difference in disease-free survival (HR = 0.60; 95% confidence interval [CI]: 0.35–1.05; P = 0.074) or overall survival (HR = 0.87; 95% CI: 0.54–1.4; P = 0.58) between IBD and non-IBD patients ( Figure 1 ). After adjusting for the propensity score, there was a trend toward significance ( P = 0.060) suggesting that IBD patients might have a better disease-free survival rate than non-IBD patients.
